"Flagging is for things that don't belong on HN."

Flagging is for flagging. Things that don't belong on HN are part of it. Redundant articles and bad discussions are others.

Even bad moods are a relevant reason to flag an article. HN is better if flagging is used to express strong emotion than toxic posting.

Yes, I agree. I do flag when discussion is toxic.
